Abstract (en)
[origin: CA3177934A1] The present invention relates to a removable electric propulsion system intended to be coupled to a rolling object. The propulsion system comprises a chassis provided with at least one wheel driven by an electric machine, and at least one non-driven wheel. Moreover, the system, preferably the chassis, comprises coupling means (5) for coupling the propulsion system to the rolling object. In addition, the coupling means comprise at least one means for combined and simultaneous gripping and lifting (100) of at least one wheel (14) of the rolling object, preferably two wheels (14) of the rolling object. The invention also relates to a method for coupling a rolling object to such a propulsion system, this method making it possible, simultaneously and by combined action, to grip and lift at least one wheel (14) of the rolling object.
